The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6966-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2024-7518, CVE-2024-7521,     CVE-2024-7524, CVE-2024-7526, CVE-2024-7527, CVE-2024-7528, CVE-2024-7529, CVE-2024-7530, CVE-2024-7531)

    It was discovered that Firefox did not properly manage certain memory operations when processing graphics     shared memory. An attacker could potentially exploit this issue to escape the sandbox. (CVE-2024-7519)

    Nan Wang discovered that Firefox did not properly handle type check in WebAssembly. An attacker could     potentially exploit this issue to execute arbitrary code. (CVE-2024-7520)

    Irvan Kurniawan discovered that Firefox did not properly check an attribute value in the editor component,     leading to an out-of-bounds read vulnerability. An attacker could possibly use this issue to cause a     denial of service or expose sensitive information. (CVE-2024-7522)

    Rob Wu discovered that Firefox did not properly check permissions when creating a StreamFilter. An     attacker could possibly use this issue to modify response body of requests on any site using a web     extension. (CVE-2024-7525)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
